Given that 0 find the value of a and the value of b.

(2 marks)

.

The values of a and b are π/2 and -1, respectively

The parent function of a sine function is:

y = sin(x)

When the function is shifted left by π/2 units, it becomes

y = sin(x + π/2)

When the function is shifted down by 1 unit, it becomes

y = sin(x + π/2) - 1

This means that the graph of y = sin(x + π/2) - 1 is the sine graph shifted left and down by π/2 and 1 unit respectively.

By comparing y = sin(x + π/2)° - 1 and y = sin(x + a)° + b, we have:

a = π/2 and b = -1

Hence, the values of a and b are π/2 and -1, respectively

Around 21.13% of the batteries will final(last) between 90.6 and 109.8 hours. 

To unravel this issue, ready to utilize the standard typical conveyance by standardizing the values utilizing the equation:

z = (x - μ) / σ

where

x is the esteem we need to discover the likelihood

μ is cruel(mean), and σ is the standard deviation.

So, for the lower conclusion of the extent, we have:

z1 = (90.6 - 105) / 12 ≈ -1.20

z1 = -1.20

And for the upper conclusion of the extension, we have the:

z2 = (109.8 - 105) / 12 ≈ 0.45

z2 =  0.45

We need to discover the rate of batteries that will final(last) between these two values, which compares to the area under the typical bend between z1 and z2.

Able to utilize a standard ordinary conveyance table or calculator to discover this zone, or we will utilize the properties of the typical conveyance to inexact it.

Since the typical conveyance is symmetric around the cruel, we know that the zone between z1 and z2 is the same as the range between -z2 and -z1 (i.e., the comparing values on the other side of the mean).

So, ready to discover the range between -z2 and -z1, which compares to the rate of batteries that will final between 90.6 and 109.8 hours:

P(-z2 < z < -z1) ≈ P(z < -z1) - P(z < -z2)

Employing a standard typical dissemination table or calculator, we discover:

P(z < -1.20) ≈ 0.1151

P(z < -0.45) ≈ 0.3264

So, the rate of batteries that will final between 90.6 and 109.8 hours is rough:

P(-z2 < z < -z1) ≈ 0.3264 - 0.1151 ≈ 0.2113

Increasing by 100%, we get:

0.2113 * 100% ≈ 21.13D

44 Subsequently, roughly 21.13% of the batteries will final between 90.6 and 109.8 hours.

There is a centered rectangular lattice but not a centered square lattice because of the different geometric properties of rectangles and squares.

A centered rectangular lattice is a lattice with one point at the center of each rectangle, while a centered square lattice would require one point at the center of each square.

However, squares have equal side lengths and angles, making it impossible for a lattice point to be centered within each square.

In contrast, rectangles have different side lengths and angles, allowing for a lattice point to be centered within each rectangle. Therefore, a centered rectangular lattice is possible, but a centered square lattice is not.

A lattice is an infinite set of points in this space with the properties that coordinate wise addition or subtraction of two points in the lattice produces another lattice point, that the lattice points are all separated by some minimum distance, and that every point in the space is within some maximum distance of a lattice point.

You’ve done bulk of the work by inserting a straight line through x.

Now, the point at which we have x, has 2 other angles

This makes 3 angles in total which add up to 360( sum of angles at a point)

36 is an alternate angle to one of the angles while 62 is also an alternate angles to one of the angles.

Since alternate angles are equal, the angles are 62 and 36

Thus the angle would be x + 62 + 36 = 360

This value represents the present worth below which the probability is 0.5, indicating a negative present worth.

To estimate the probability that the present worth is negative using the NORM.INV function in Excel,

we need to calculate the present worth of the project and then determine the corresponding probability using the normal distribution.

The present worth of the project can be calculated by finding the sum of the present values of the annual receipts over the 10-year period, minus the initial investment. The present value of each annual receipt can be calculated by discounting it back to the present using the minimum attractive rate of return (MARR).

Using the given information, the present value of the initial investment is $10,000. The present value of each annual receipt is calculated by dividing the expected return of $1,800 by \((1+MARR)^t\),

where t is the year. We then sum up these present values for each year.

We can use the NORM.INV function in Excel to estimate the probability of a negative present worth. The function requires the probability value, mean, and standard deviation as inputs.

Since we have a mean and standard deviation for the present worth,

we can calculate the corresponding probability of a negative present worth using NORM.INV.

This value represents the present worth below which the probability is 0.5. By using the NORM.INV function,

we can estimate the probability that the present worth is negative based on the given data and assumptions.

R is (4,0) which when reflected across y = x is (0,4)

The given information leads to an inconsistent system of equations. There is no value of  that satisfies the given conditions.

We can start by identifying the given information - The parabola has a vertical line of symmetry at x = -3- The parabola goes through the two points (-2, 0) and (4, 0)- The quadratic has two real roots.

Since the parabola has a vertical line of symmetry at x = -3, the x-coordinate of the vertex is -3. The y-coordinate of the vertex can be found by substituting x = -3 into the equation of the parabola.

Now, let's find the equation of the parabola using the given information:
Since the parabola has a vertical line of symmetry at x = -3, the equation of the parabola can be written in the form:
(x - h)² = 4p(y - k),

where (h, k) is the vertex and p is the distance between the vertex and the focus.

Substituting (-2, 0) into the equation, we get:
(-2 + 3)² = 4p(0 - k)
(1)² = -4pk

Substituting (4, 0) into the equation, we get:
(4 + 3)² = 4p(0 - k)
(7)² = -4pk

Now, we can solve the system of equations:
1 = -4pk
49 = -4pk

Dividing the second equation by the first equation, we have:
49/1 = -4pk/-4pk
49 = 1

Since this is not possible, it means that the information given is inconsistent. There is no solution to this problem.

The given information leads to an inconsistent system of equations. Therefore, there is no value of  that satisfies the given conditions.

The two roots are x = -2 and x = 0. Since the question states that the greater root is -2, the value is -2.

Explanation :

The equation of a parabola with a vertical line of symmetry can be written in the form y = a(x - h)^2 + k, where (h, k) represents the coordinates of the vertex. In this case, the line of symmetry is x = -1. Since the vertex lies on the line of symmetry, the x-coordinate of the vertex is also -1.

We are given that the parabola passes through the points (-2, 0) and (0, 8). By substituting these coordinates into the equation, we can form two equations:

0 = a(-2 - (-1))^2 + k
8 = a(0 - (-1))^2 + k

Simplifying these equations, we get:

0 = a + k
8 = a + k

Combining the equations, we find that a = 4 and k = -4. Therefore, the equation of the parabola is y = 4(x + 1)^2 - 4.

To find the roots, we set y = 0 and solve for x:

0 = 4(x + 1)^2 - 4
4(x + 1)^2 = 4
(x + 1)^2 = 1
x + 1 = ±1

Kindly check explanation

Step-by-step explanation:

Given that :

Total flowers sold = 200

Flowers are :

Carnations, Roses, and Gerber daisies

Carnations = c

Roses = r

Daisies = d

20 fewer roses than daisies ; r = d - 20

Total sales = $453

c = $1.50 each ; r = 3.75 each ; d = 2.25 each

c + d + d - 20 = 200

c + 2d = 220 - - (1)

1.50c + (d - 20)(3.75) + 2.25d = 453

1.50c + 3.75d - 75 + 2.25d = 453

1.50c + 6d = 528 - - - (2)

From (1)

c = 220 - 2d

1.5(220 - 2d) + 6d = 528

330 - 3d + 6d = 528

330 + 3d = 528

3d = 528 - 330

d = 198/3

d = 66

66 × 2.25 = $148.5

c = 220 - 2(66)

c = 88

88 * 1.50 = $132

r = d - 20

r = 66 - 20

r = 46

46 × $3.75 = $172.5

Answer:

(-2,2)

Step-by-step explanation:

First, let's look at the 2 inequalities:

y ≤ -x + 1

y > x

Just by looking at the second inequality, we can remove any ordered pairs where x is greater than or equal to y. This eliminated the ordered pairs (-1,-3) and (0,-1). Now, the answer has to be (-3,5) or (-2,2). Knowing this, we can plug x and y into the equation and see if either of the answers are true.

(-3,5):

x = -3

y = 5

y ≤ -x + 1

5 ≤ -(-3) + 1

5 ≤ 3 + 1

5 ≤ 4

NOT TRUE

(-2,2)

x = -2

y = 2

2 ≤ -(-2) + 1

2 ≤ 2 + 1

2 ≤ 3

TRUE

So, since plugging in the ordered pair (-2,2) into the inequality gives us a true answer while (-3,5) doesn't, the order pair (-2,2) must be out answer.

The missing step in solving the inequality 4(x – 3) + 4 < 10 + 6x is step 6: The division property of inequality: x > -9

The missing step in solving the inequality 4(x – 3) + 4 < 10 + 6x is step 6: The division property of inequality.

After step 4, which is -2x < 18, we need to divide both sides of the inequality by -2 to solve for x.

However, since we are dividing by a negative number, the direction of the inequality sign needs to be reversed.

Dividing both sides by -2:
